• Install an audio encoder using MediaRecorder.setAudioEncoder ()
• Call MediaRecorder.prepare () on the MediaRecorder instance.
• To start recording audio, call MediaRecorder.start ().
• To stop capturing audio, call MediaRecorder.stop ().
• When you are done with the MediaRecorder instance, call MediaRecorder.release () on it. calling MediaRecorder.release () is always recommended to release the resource immediately.
